Witnesses at the show took to social media to describe what they called a gruesome scene Thursday night. They said the fan fell off a second-story balcony.
The Palladium does have balcony seating, but it remains unconfirmed exactly where the person fell from and why.
The fan was loaded onto a gurney and taken away in an ambulance. The person's identity and condition were not immediately released.
Blink 182 played sold-out shows on both Wednesday and Thursday. They will be playing at the Wiltern Theater for three nights starting Nov. 11.
